Dimensional contraction via Markov transportation distance [PDF]
, 2013 It is now well known that curvature conditions \`a la Bakry-Emery are equivalent to contraction properties of the heat semigroup with respect to the classical quadratic Wasserstein distance.

Finite coverings of semigroups and related structures [PDF]
International Journal of Group Theory, 2023 For a semigroup $S$, the covering number of $S$ with respect to semigroups, $\sigma_s(S)$, is the minimum number of proper subsemigroups of $S$ whose union is $S$.

Cross-connections and variants of the full transformation semigroup [PDF]
, 2017 Cross-connection theory propounded by K. S. S. Nambooripad describes the ideal structure of a regular semigroup using the categories of principal left (right) ideals.

Linear growth for semigroups which are disjoint unions of finitely many copies of the free monogenic semigroup [PDF]
, 2015 We show that every semigroup which is a finite disjoint union of copies of the free monogenic semigroup (natural numbers under addition) has linear growth.

On transformation semigroups which are ℬ𝒬-semigroups
International Journal of Mathematics and Mathematical Sciences, 2006 A semigroup whose bi-ideals and quasi-ideals coincide is called a ℬ𝒬-semigroup. The full transformation semigroup on a set X and the semigroup of all linear transformations of a vector space V over a field F into itself are denoted, respectively, by T(X)

On the closure of the extended bicyclic semigroup
Karpatsʹkì Matematičnì Publìkacìï, 2013 In the paper we study the semigroup $\mathcal{C}_{\mathbb{Z}}$ which is a generalization of the bicyclic semigroup. We describe main algebraic properties of the semigroup $\mathcal{C}_{\mathbb{Z}}$ and prove that every non-trivial congruence $\mathbb{C}$

Proceedings of the American Mathematical Society, 1977 A Tarski semigroup is an algebraic system which mirrors a fragment of the additive theory of cardinal numbers. Here we show that any two such systems have the same universal theory. We also give a simple arithmetical necessary and sufficient condition for a universal sentence to hold in a Tarski semigroup.

Frequently Hypercyclic and Chaotic Behavior of Some First-Order Partial Differential Equation
Abstract and Applied Analysis, 2013 We study a particular first-order partial differential equation which arisen from a biologic model. We found that the solution semigroup of this partial differential equation is a frequently hypercyclic semigroup.

Journal of Algebra, 2000 In earlier articles of the first author it was shown how to construct an inverse semigroup from any tiling of Euclidean space. Such semigroups are called tiling semigroups. In the paper a categorical basis for such constructions is given in terms of an appropriate group acting partially and without fixed points on an inverse category associated with ...

Finite groups are big as semigroups [PDF]
, 2011 We prove that a finite group G occurs as a maximal proper subsemigroup of an infinite semigroup (in the terminology of Freese, Ježek, and Nation, G is a big semigroup) if and only if |G| ≥ 3.
